Creating precise stone seats is very easy when you use the Busch® 413AU style carbide burs.
The bur drills the perfect shape for the base of the facetted stone and ensure that it sits firmly. You will find the AU line of High Tech Carbide burs from Busch® will all cut more aggressively than standard carbides. Especially with hard materials such as platinum, titanium and white gold, it shows its strength.
The tungsten carbide stone setting bur impresses with its outstanding durability.
